F-Phenibut FAA (4-Fluorophenibut free amino acid) is a several-fold more potent derivative of Phenibut. Phenibut is an atypical anxiolytic and nootropic compound structurally similar to the well known inhibitory neurotransmitter GABA, as well as to baclofen (β-(4-chlorophenyl)-GABA) and pregabalin (β-isobutyl-GABA). Phenibut was originally thought to act solely as a selective GABAB receptor agonist, similar to its much more potent relative baclofen, but has more recently been found to additionally act with somewhat higher affinity as an inhibitor of α2δ subunit-containing voltage-gated calcium channels, a mechanism of action shared with gabapentin and pregabalin.
